About our sand mastic in Thanington
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. If you have crumbling sand mastic round a window and cracked mastic round a front door frame, we can put it right, on tenement windows, brick reveals and timber door frames alike.
Houses in smaller places like Thanington can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
There’s a 12-month guarantee on every job, large or small.

What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. In an older home around Thanington, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Combining jobs into one visit is normally more efficient than separate visits. We’ll give you a clear price for the lot.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Make sure water runs off the sill
- Ask a joiner to look at soft timber first
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
How it works
We keep the work tidy and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours per window, depending on the condition of the joints, and we explain the cure time before we leave. Parking around Thanington is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on

Advice
For landlords and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Surface by surface
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Thanington homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Nicholas include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as The Canterbury Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
